I got this years ago after i had a very difficult pregnancy. I devoured this in days, searching for ways to prevent the first experience, if i could. I followed everything faithfully and was amazed at the results! My approach has always been, "If it is true, it will work. I may not understand how or why, but the proof is in the pudding." I became such a believer, that i followed it every time, and never again experienced the first horror.
